XPath expression failed to execute. Error while processing xpath expression

If you get this exception while deploying your bpel process, there could be some issue with the xsl file that you have in your bpel process.

To fix this issue, open your bpel process in IDE and double click on the transform activity and click on source part payload and target part payload. Then you deploy.


Before loading the source part and target part if you close the transform box, these kind of issues will stop you from deploying.
